[AT] Got a question about a Waukesha engine (F-12)

[John Wilkens]

I've been putting out  requests to various sources for an answer to 
this question but no hits yet.  Wonder if you ATIS guys might give me 
a clue about a part on my F-12 Waukesha engine.  There is a 1/2" 
(about) stud in the lower left side of the block that goes through 
the lower radiator tube elbow to secure the elbow to the block.  The 
bolt is loose in the block--sorta fastened inside with some lead or 
solder.  For some reason there is a piece of copper tubing fastened 
around part of the bolt??  Anyway, is this bolt in a blind hole, or 
if it is loose can antifreeze get into the inside of the 
crankcase?  Any help appreciated!   John
